Little League Baseball has adopted a new bat standard effective January 1, 2018. Current Little League-approved baseball bats can be used through December 31, 2017, but will not be permitted for any Little League practices or games beginning January 1, 2018. Also, current baseball bat regulations are in effect until then. That includes the moratorium prohibiting the use of all 2 1/4" barrel baseball bats constructed with composite material in the barrel, unless approved.
